The US is compiling information on the drone attack in Moscow, a National Security Council spokesperson said, while stressing the US does not back attacks in Russia.
"We saw the news and are still gathering information about what happened," the council's spokesperson said. "As general matter, we do not support attacks inside of Russia."
Russia blamed Ukraine for the drone attack in Moscow, while Ukraine has denied any direct involvement.
The NSC spokesperson also criticized Russia for launching an overnight aerial assault on Kyiv — the 17th this month.
"We have been focused on providing Ukraine with the equipment and training they need to retake their own sovereign territory, and that’s exactly what we’ve done. Today was also Russia’s 17th round of air strikes on Kyiv this month, many of which have devastated civilian areas, as Russia continues its brutal attacks against the people of Ukraine," the spokesperson said.
"Russia started this unprovoked war against Ukraine. Russia could end it at any time by withdrawing its forces from Ukraine instead of launching brutal attacks against Ukraine’s cities and people every day," the spokesperson said.
